Comment 1 for bug 1581237

There are conditions of Deploy Changes button visibility:
https://github.com/openstack/fuel-ui/blob/stable/mitaka/static/models.js#L368-L372

If the cluster has 'partially_deployed' status, then we should check it's release availability or we need to be sure there is no running deployment task.

Can not reproduce the issue on dev environment (fake Nailgun): http://s32.postimg.org/ebia5y22t/Screenshot_from_2016_05_13_10_07_41.png

Alexey, could you please provide screenshots of the cluster Dashboard and Nodes tabs after stopping of nodes deployment? An ability to research the live environment would be great.
